A constabulary was first formed under the Cheshire Constabulary Act 1829 (10 Geo. 4, c.97) which was amended by the Cheshire Constabulary Act 1852. The passage of the County and Borough Police Act in 1856 led to the dissolution of this force and the creation of a second Constabulary. Many of the officers continued to serve in the new force and there was clauses in the Act which allowed their pension rights to continue.

The first Chief Constable was Captain Thomas Johnnes Smith, late of the Bedfordshire Militia. The first full Cheshire Police Committee met at the Crewe Arms Hotel, Crewe, on 3 February 1857 and the new Cheshire Constabulary was officially formed on 20 April 1857.[4]

The first Headquarters was established at 4 Seller Street, Chester. In 1862 this office was removed to 1 Egerton Street, Chester and remained there until 1870, when it was removed to 113 Foregate Street. In 1893 the Court of Quarter Sessions approved the building of a new Headquarters which was erected at 142 Foregate Street and designed by John Douglas, at a cost not exceeding £2,000. This continued to be used, together with the adjoining buildings, until 1967, when a new purpose-built Headquarters was opened at Nuns Road, Chester. This building served the Constabulary until 2004 when the Headquarters building moved to a purpose-built complex at Clemonds Hey, Winsford.[4] In 1965, the force had an establishment of 1,359 and an actual strength of 1,329.[5]

It was proposed by the Home Secretary on 6 February 2006 that Cheshire should merge with the Merseyside Police, to form a strategic police force,[6] but these proposals were later abandoned.

The Museum of Policing in Cheshire preserves and researches the heritage of policing in the county.

The current Cheshire Police and Crime Commissioner is David Keane. From the 15 November 2012 to the 5th of May 2016, John Dwyer held the office. The police and crime commissioner is scrutinised by the Cheshire Police and Crime Panel, made up of elected councillors from the local authorities in the police area. Before November 2012 the Cheshire Police Authority was the police governance.

Local Policing Units (LPUs), each with local Neighbourhood Policing Teams and investigation teams. The LPUs concentrate on responding to emergency/non emergency calls, preventing and detecting local crime and targeting offenders, building contacts in the local community, resolving problems by working with local organisations and individuals, and being visible and accessible.

Custody Investigation Teams(CIT), consist of a combination of interviewing Police Officers and Civilian Staff members who interview persons detained in the Custody Suite suspected of committing an offence.

The Cheshire road system is made up of 3,417 miles (5,499 km) of highway. The constabulary is responsible for policing one of the longest stretches of motorway in Britain. The force patrols 214 miles (344 km) of the M6, M62, M53 and M56 motorways, which has 23 interchanges and 4 service areas. The M6 motorway across the Thelwall Viaduct carries 140,000 vehicles every 24 hours. Delays and incidents on the motorway can have a severe impact on the economic life of the entire North West Region.[7]

Cheshire Constabulary is responsible for policing the annual Creamfields dance and music festival that takes place over the August bank holiday weekend every year at Daresbury in Halton, close to Runcorn and Warrington.

Since December 2001 Cheshire Police have operated a Britten-Norman Islander fixed-wing aircraft, registration G-CHEZ. This model of aircraft is used worldwide in a variety of roles. It is particularly suited to police aviation as it is able to carry a wide range of equipment and stay airborne for long periods of time. This equipment allows it to operate during the day or night, in most weather conditions. It is cleared for flight in cloud and bad weather, but the majority of police operations require visual contact with the ground. If required, it can carry up to six persons.

The aircraft is operated by a team of civilian pilots, four police observers and one sergeant ensure the aircraft is available all year. The aircraft is used to conduct a wide range of policing work providing emergency responses to incidents involving threat to life, commission of crime and searching for missing persons. It also conducts deployments for non-crime searches, scene management at incidents and video evidence gathering.

On 27 February 2009, the Constabulary confirmed that the Home Office had agreed to jointly fund the purchase of a new £1 million Eurocopter EC135 aircraft, to be operational 24 hours a day.[8]

On 18 July 2011, the North West Air Operations Group (NWAOG) was launched. The NWAOG is a regional collaboration between five forces and police authorities. The service dispatches aircraft from a regional command desk to incidents across Cheshire, Greater Manchester, Lancashire, Merseyside and North Wales.

The five forces in the North have four helicopters, based at four different locations throughout the North West, providing a service anywhere in the region, 24 hours a day, 7 days a week.

With 24-hour cover, the collaboration will enable the five forces to cope better with demand, with efficient use of all four helicopters, whilst enabling forces to make further savings and maintain resilience across the region. This is a move away from the concept of having one helicopter serving one region, to adopting the identity of one unit with support provided to all five forces

The collaboration allows for considerable savings, while offering an improved air support service. Benefits of the arrangement include the facility to have the closest helicopter deployed quickly to any incident and if there are two incidents in the same force area, then two helicopters can be deployed as necessary.
